Abstract

Eine Vorrichtung zur Erzeugung von Druckpulsen in einem einen Bohrrohrstrang (1) abwärts durchströmenden Bohrspülungsmedium umfaßt ein in dem Bohrrohrstrang (1) angeordnetes Ventil mit einem axial verschieblichen, rohrförmigen Hauptventilkörper (4), einem koaxial im Hauptventilkörper (4) angeordneten, ortsfesten, rohrförmigen Trägerkörper (5), der im Überlappungsbereich mit dem Hauptventilkörper (4) mit diesem einen zylindrischen Spalt (18) begrenzt, und einem mittels eines Antriebs (15) betätigbaren Hilfsventil (13, 14). Der Außenteil (3) und der Hauptventilkörper (4) begrenzen zwischen sich eine Drosselstrecke (28) mit in Abhängigkeit von der Stellung des Hauptventilkörpers (4) veränderlichem Durchflußquerschnitt, und der Hauptventilkörper (4) und der Trägerkörper (5) umgeben einen Innenströmungskanal (21, 12, 10), dessen Eintrittsöffnung (25) zentral in dem Stirnteil (22) des Hauptventilkörpers (4) vorgesehen und dessen Austrittsöffnung (13) zentral an dem unteren geschlossenen Fußteil (8) des Trägerkörpers (5) angeordnet und mittels des Hilfsventilkörpers (14) freigeb- und verschließbar ist. Dabei ist der Spalt (18) zwischen dem Hauptventilkörper (4) und dem Trägerkörper (5) von Bohrspülungsmedium frei durchströmbar und bildet im Überlappungsbereich eine enge Drosselstrecke (29;30). A device for generating pressure pulses in one Drill pipe string (1) flowing down drilling fluid comprises a in the drill pipe string (1) arranged valve with an axial Slidable, tubular main valve body (4), a coaxial in the Main valve body (4) arranged, fixed, tubular Carrier body (5) in the overlap area with the main valve body (4) with this one cylindrical gap (18), and one auxiliary valve (13, 14) which can be actuated by means of a drive (15). The The outer part (3) and the main valve body (4) delimit one between them Throttle section (28) with depending on the position of the Main valve body (4) variable flow cross section, and the The main valve body (4) and the carrier body (5) surround one Inner flow channel (21, 12, 10), the inlet opening (25) centrally provided in the end part (22) of the main valve body (4) and its Outlet opening (13) centrally on the lower closed foot part (8) of the carrier body (5) and by means of the auxiliary valve body (14) can be released and locked. The gap (18) between the Main valve body (4) and the carrier body (5) of drilling fluid freely flowable and forms a narrow one in the overlap area Throttle section (29; 30).
